Thread: [Matplotlib-users] tex rendering broken?

I am having trouble executing the example for typesetting labels with
latex from http://matplotlib.org/users/usetex.html. Copying the standard
example, tex_demo.py, to a file and executing it gives the following
output:

My matplotlib version is 1.3.1, and I am using standard packages from my
Ubuntu 14.10 distribution.

I just installed matplotlib 1.4.2 via pip, and executing the file
matplotlib-1.4.2/examples/pylab_examples/tex_demo.py from the source
tarball gives the same error:

I just downgraded to matplotlib 1.1.1 and now everything works. Looks
like a regression to me.

My first guess is that there is that some thing wrong with your latex
installation as the images on the website are regenerated as part of
building the documentation.

I can not reproduce this problem on a 1.4.2 installation on my computer.
Try cleaning out the tex.cache folder in either or both of
matplotlib.get_cachedir() or matplotlib.get_configdir().

Thanks. Clearing the cache directory did the trick. It might be a good
idea to mention matplotlib.get_cachedir() and matplotlib.get_configdir()
explicitly under 'Troubleshooting' on the web page. Currently there is a
link which points you to matplotlib.get_configdir() (which was empty in
my case) but not matplotlib.get_cachedir().

Best regards,
Martin.
